flask.helpers flash Example Code

flash is a function within the flask.helpers module of the Flask framework. flash passes a string message to the next request. The following request can access it in a template by using the get_flashed_messages function.

flash can also be imported directly from the flask module instead of flask.helpers so you will often see that shortcut in example code.

get_root_path, make_response, safe_join, send_file, and url_for are several other callables with code examples from the same flask.helpers package.
